RETURNING MECHANISM FOR HAY-CARRIERS.

Specification of Letters Patent.

Patented Dec. 29, 1908.

- Application filed May 18, 1908. Serial No. 433,598.

T 0 all whom it may concern:

Be it known that I, NELS J OHNSON, residing at Hunter, in the county ofCass and State of North Dakota, have invented a new and ImprovedReturning Mechanism for Hay- Carriers, of which the following is aspecification.

vide a simple and effective means for automatically returning a haycarrier back in position to look after the same has been tripped to dumpthe load, and my said invention comprehends, generally, a flanged wheelor sheave to which one end of the carrier rope is fastened to windthereon, said sheave being loosely mounted on a shaft, and a springdevice that is fixedly connected at one end to the shaft and at theother end to the wheel in such manner that when drawing the carrier ropeforwardly, for dumping, tension is applied on the spring that serves torotate the wheel and Wind up the rope to pull the carrier back to lockinto the track after the load is dropped and the hay line is un hitched.

In its subordinate features, my invention consists in certain details ofconstruction and peculiar combination of parts, all of which will befully explained, specifically pointed out in the appended claims andillustrated in the accompanying drawing, in which,

Figure 1, is a vertical, longitudinal section of my invention, the pulldirection of the rope being indicated by the full line arrows, and theautomatic return direction indicated by dotted line arrows, the saidview being taken on line 11 on Fig. 2. Fig. 2, is a transverse verticalsection thereof. Fig. 3, is a perspective view of one of the shaft supports B. Fig. 4, is a perspective view of the actuating springhereinafter referred to.

In the practical application of my invention, when the same is used in abarnhaving a hay fork, it is preferably mounted adjacent the hay doorand alongside of the usual track, and the same is supported on bedplates 13-13 that are secured at their ends by bolts that attach them tothe track supporters, as indicated in Fig. 1.

Mounted on the bed lates BB is a shaft 0. that is fixedly he d thereonby the bolts and nuts as clearly shown in Figs. 1 and 2, by reference towhich it will be also observed that upon the shaft a is loosely mounteda flange wheel or sheave A having spokes set to one side of the rim,whereby to provide for an internal space to. receive the helical orclock spring C, one end of which is fastened to the shaft and its otherend is fastened to the inside face of the wheel rim, My invention hasfor its purpose to prothe latter having annular inwardly extendingflanges whereby to provide an annular socket in which seats theoutermost coils of the springs and which serves to properly guide thesaid s rings and take off undue lateral strain at t e outer orcircumferential portions thereof.

From the foregoing, taken in connection with the drawing the completearrangement, the manner of use and the advantages of my invention willbe readily apparent.

I have not shown the carrier or the loader, or the locking device thatholds the carrier locked, pending the delivery of the holder to thepoint of discharge, since these parts are a wellknown type and requireno special assembling of parts to render my invention operable.

It will be noticed that my invention is exceedingly simple and since itsreturning action is almost entirely automatic it effects a considerablesaving of time and labor for unloading the hay and carrying it to thepoint of delivery.

While I have particularly described my invention as especially adaptedfor returning the hay carrier to its starting point, it may be used forvarious other purposes, where no returner power is used.

Having thus described my invention, what I claim and desire to secure byLetters Patent is g 1. The combination with a suitable support, a shaftfixedly held thereon, a flanged wheel loosely mounted on the shaft, saidflanged wheel also having inwardly projecting flanges, a helical springhaving one end secured to the shaft, wound about the shaft, its free endbeing made fast to the internal rim of thewheel; of a carrier pull rope,and guides therefor, said rope taking around the wheel and having oneend fastened to the rim thereof.

2. The combination with hangers, a pair of bed plates mounted upon thelower ends of the hangers, a shaft disposed transversely of and fixedlymounted upon the said bed plates, a flanged Wheel loosely mounted on theshaft, said wheel h aving inwardly eX- tended annular flanges whereby toform an annular internal socket, a helical spring mounted in the saidsocket, one end of which is secured to the internal rim of the wheel,
